There Are Just So Many Questions I have for These Two

Here’s what I need to know:
how do you deal with boyfriends? Do you both have to like the same guy?
When you get angry at each other do you head butt each other?
How do you deal with driving? What if one sister wants to go one way and the other sister wants to go the other?
How do you take tests in school? Do you whisper the answers to each other?
What happens if one sister gets the flu and is all puke-y?
